An audio review & news blog. The volume should not exceed 80 dB is recommended. I usually adhere to the safe-listening style by WHO. Please note that my aural impressions and interpretations of measurements are also made from a safe-listening style.
The EPZ Q1 earphones have a full midrange sound with very controlled high frequencies. It is well designed and well packaged, and may be recommended as a very comfortable listening earphone for those who are sensitive to high frequencies.
